part of this specification.

' This invention relates to window guards and consists of the mattershereinafter described and more particularly pointed out in the appendedclaims.

The object of the invention is to provide a guard for windows which maybe readily and easily attached to a window and its associated casing, orwhich may be detached therefromby one within the room in whichv thewindow is'located when the window is closed, but which is securelylocked in a position of security and safety when the window is open, nomater how small the opening," so that it cannot be removed either from aposition inside or from a position outside of the window.

In the drawings :Figure l is a view in elevation as looked at from theinside of a building, of a window casingor frame with the usual upperand lower window sashes thereof in a closed position, and with myimproved window guard attached in proper position. Fig. 2 is afragmentary view of the same in elevation on an enlarged scalevillustrating the position the guard assumes when the lower window sashis in a raised position. Fig. 3 is a detail vertical section on anenlarged scale, the plane of the section being indicated byline 3-3 'ofFig. 2. Fig. 4'isa' detail perspective view of 'theupper left-handcornerof the lower window sash and its surroundings showing a part ofthe-window guard, attached thereto, Fig. 5' is a detail perspective viewof a channel which forms part of the attaching means forthe windowguard. Fig. 6 is a view in. perspective of the guard as it appears whendetached from the window. Fig. 7 is a detail .plan sectional view, theplane of the section being indicated by line 77 of Fig. 4. Fig. 8represents a view similar to that shown in Fig. 7 with the parts in{changed relation.

Referring now in detail to that embodi-.

ment of my invention illustrated in the accompanying drawings, 10indicates a window casing or frame, and 11 the usual horizontal sillmember forming a part thereof. The said casing is provided with theusual upper and lower sash members 12 and 13 which are adapted forvertioal'sliding move-' ment insuitable guides or runways forming a partof said casing. v

14, 14 indicate vertically arranged channel members which are attachedto the inner faces of the upright side members 13*, -13 of the lowerwindow sash 13. Each of said channels 14, 14, are of a lengthapproximating the vertical height of the upright member 13 13 of thewindow sash 13 and consists of a body member 14 of U-shapeincrosssection and having laterally extending flanges 14", 14 whichengagewith the sash members 13 15 and by means of which said channels14, 14, are fixed to said sash members. Each, body member 14 is providedwith a slot 15 which extends approximately from top to bottom of said.members, is closed at both ends and has an enlarged hole 15 at its upperend.

16, 16 indicate anchor plates fixed to the window sill 11. Said platesvare arranged to cover laterally spaced recesses 17 formed in said sill,at a suitable distance from the plane of the lower sash 13. Said platesextend a short distance beyond the lateral edges of the recess 17 andare attached to said sill by means of screws "16 the'upper surfaces ofsaid plates being preferably made flush with the upper surface Ofsaidsill member 11. Each of said plates 16 has an aperture 16 the purposeofwhich will appear as I proceed withmy specification.

"20' indicates as a whole my improved window guard (see Fig. 6) which isof a height aiidwidth approximating the height-and width of the lowerwindow sash 13. :Said

guard has-an open frame which comprises,

as shown, upright side members 21, 21 and top and bottom horizontalmembersx22, 23.

The frame is closed by a grating for other like device which is capableof freelyadmitting lightand air while at the same time preventing thepassage through the frame of persons or children from the inside or ofburglars or thieves from the. outside.

In the drawings the frame 20 is shown as beingclosed by a gratingmade-of upright laterally spaced bars 241 which are attached at theirends "to the topand bottom hori ber25 is preferably so arranged as tobind zontal members 22, 23 of the frame 20. To strengthen and brace theframe as a whole, a centrally disposed horizontal bar or memthe sidemembers 21, 21 and the upright spaced bars 24 together. The WlIlCl-OWguard is removably attached to the window sill .11 and to the lower sashmember 13 in such a way that the lower sash may be raised freely a' sdesired and when said sash is in raised position, the security of theguard is assured against removal either frominside or from outside thewindow. The preferred way of attaching said guard '20 is as follows: Thebottom frame member 23 of the window guard is provided with depending,inwardly projecting, hook members 26. As

shown in the drawings, the said hook mem bers are'formed by extendingthe lower ends of two of the grating bars 24 below the horizontal bottomframe member 23 and bending the same inwardly to form hooks 26, 26', asillustrated'in Fig. 6. The "said hook members .26 are adapted to beinserted into the apertures '16 formed in the anchorplatesfl 6,-fixed tothe sill 11, so that when the window-guard 20 is swung into an uprightposition, the said hooks lie within the recesses 17 formed in the sill11. Said hooks are made long enough so that when the guard rests uponthe window sill, the'hooked ends there-of will rest somewhat below theanchor plates '16. The upper ends of the upright'side frame members 21,21 extend beyond the upper surface of the horizontal "top frame member22 and are bent in a direction opposite'to thatof the hook membore 26to, form outwardly extending horizontal'hook members 27, 27. Each hookmember 27'is reduced in diameter near its free end to form a neck 28-and when said frame isin an upright operative position said heck 28operatively engages within and has sliding bearing between the wallsdefining the lateral edges of the slot 15 formed i i-the channel member14..

The'window guard :20 is attached to a window sin-provided with theanchor-plates a window sash provided with the .channels 14, 14:, inthefollowing manner.

f'fllhe lower window sash 1'3must'be inits closed position and the frame20" is then held in-front of said sash with its upper-end'in'cliinedl-toward the interior of the room. The-bottom frame member 23'is then moved tobrirrg its inner edgeintoj'engagement with -th'e rinner"margin :of the anchor-plates 16 (see-Fig; 3) and when inthis positionthe 1 .ihook-me'mb'e rs 26 are inserted into the apertures 16 er saidanchor-plates '16,. The frameis then swung about the inner edge aof thebottom frame member 523 as an axis,

into a vertical position which movement Lhnin'gs the hooks 26, 26withinthe recesses 17 mama-a1. :tlreawindow sill Jill. ..The;tframeplate 16. 1

' lVhen 1t is desired toraisethe lower sash v 1.0

is-then' in a position permitting a slightplay in a vertical directionbut cannot be withdrawn in that manner. When in a vertical position thebottom frame member 23 completely covers the plates 16, 16 in the sill.

Vith the window guard in this position'the ends of the hook members 27,27, engage that portion of the body member 14 of the channel members 1 1defining the lateral edges of the slots 15 adjacent the enlargements l5-at the upper ends thereof. When in thisposition the said hook memberscannot be inserted into the interior ofthe'channel 141-. The windowguard is now slightly raised the engagement of the hooks 26 with theanchor plate 16 permitting such movement) until the outer end of'th'ehooks 27 with the enlargements 15 of the slots 15- and the frame is thenswung about-its lower edge as an axis when the hooks 26 may bedisengaged from the apertures in the 13. with the window guard 20 inplace, said guard in no manner interferes therewith.

The sash in rising carries with it its asso .ciated channels 14, 14which channels will end hook members 27 so-that the guard ca n not bewithdrawn or removed when'the sash is raised. Y It is apparent that awindow guard-made always be in position to. guide and hold the; a A

in accordance with my invention can be'readi l-y and easily attached toor detached from the window sash and casing by a person from within theroom and cannot be removed from the outside. :This: is. advantageousinasmuch as the housewife can quickly' detach V the window guard for thepurposeof-washing. windows or the like and replace the 'same'when ready,without the necessity of Imanipulating catches, springs, or other doVlCGS, the operatlon of which she may not be familiar with. The guardrests cl oseto the window sash,is not int'he way for thev windowcurtains anddoes not present -an" unslghtly appearance from the outside.The

guard is always in a position of securityand safety no matter how farthe sash is' ra'i'sed andthe only time that said guard can-be re- I*moved from the window to whidh it is attached 31S when said windowisclosed.

While in describing my inventiom-fl referred toicertam details ofmechanical eonstruction and arrangement, it is to be understood that theinvention is not limited there to, except as may be pointed out in theappended claims.

I claim as my invention:

1. A window guard adapted to be secured at the inside of a windowcdmprising in combination with the window sill and the lower windowsash, an" open frame, a covering for the said frame, means fordetachably engaging the bottom of said framewith said window sill,vertically extending guide members on said Window sash, and devices ator near the upper end of said frame adapted for locking and guidingengagement with said guide members.

2. A window guard adapted tobe secured at the inside of a windowcomprising in combination with the window sill and the lower Windowsash, an open frame, a grating covering said frame, apertured platesfixed to said window sill, the said window sill being provided withrecesses below said plates, means provided at the bottom of said framefor engagement in the apertures of said plates, vertically extendingslotted channel bars fixed to said sash, the slots in said channel barsbeing closed at their upper ends and being enlarged at said upper ends,and devices provided at the top of said guard frame adapted forinsertion through the enlarged upper ends of said slots and for lockingand guiding engagement Within said slots when said window sash israised.

In testimony that I claim the foregoing as my inventionI affix mysignature in the presence of two witnesses, this 7th day of April A. D.1914. I s
